Abstract

Heavy metals (Cu, Zn, Pb, Cd, Fe, ?n) have been studied in spring waters in order to assess any toxicological problem. The analysis were realized by Atomic Absorption Spectroscopy. The results showed that the water was not dangerous for human health, so the metals considerated as toxics (Cd, Pb) did not present problems of contamination. The other metals had values below the maximum admisible concentration, except Mn, which presented concentrations above the maximum admisible concentration in six spring waters.
